How to remove freezer door from fridge with freezer underneath

have a french door/freezer underneath model LRFXC2606S

one of the metal slides has seized up so the freezer only partially opens, not enough to remove racks. I can see a screw on the good side rail that looks like it would disassemble the freezer door, but the seized rail is blocking the other side's screw. If I could remove the freezer door, I could get to the seized slide.

Is there other screws to remove the door from the sliding rails?

Is there another disassembly option besides me cutting through the bad rail to reach the screw?
